BRIDGE-SCORING DEVICE.

Application filed-June 6, 1927, Serial No. 196,967, and in Denmark 'May18, 1927.

. Score-keeping in the game of bridge is eected by recording', on asheet of paper,

above and below a horizontal line on the same as the case may be, thepoints scored by the two or three playing parties, for each party in aseparate column,`whereafter the account is made up later onby additionof the thus ,recorded point numerals' in accordancerwith the rules ofthe game.

This score-keeping requires much care in order to prevent disagreementsbetween the players, and the present invention has for its object tofacilitate the score-keeping. According to the invention the account iskept solely by adjustment of slides or the like on a special support,base, or board whereby any recording of points etc. on paper will berendered superfluous, the players being at the same time enabled toascertain at any moment,

simply by direct inspection of the board, the

precise state of the game.

One construction of such apparatus in board-shapev is illustrated on thedrawing,

where Fig. l shows the scoring board in zero-position, i. e. at thecommencement of the game,

Fig. 2 is a longitudinal section along the line II-II of Fig. 1.

Fig. 3 is a cross-section along the line III- III of Fig. 1.

Figs. 4 and 5, show di-agrammatically, the adjustment of the scoringboard at a certain moment during the rst played game and after the finalclosure of the same, respectively, i. e. at the commencement of the nextgame.

In-order to avoid crowding the drawings Ionly a few of the numerals ofthe scales have been indicated, and these numerals are placed outside ofthe figure concerned.

In the construction shown, the scoring board is rectangular and isprovided, on its left-hand side, with seven grooves or tracks parallelto the long side of the board (the two inner ones and the two outer onescovering one another in pairs) and slides inserted' sponding to theiradversaries. In the following only one/.of the two similar sets ofslides will be described.-

A direct registration of scored points above the line i. e. above atransverse line drawn on the surface of the board, which pointsaccording to the rules of the game are often a multiple of 50, iseffected by means of the central slide b which in its zero-position isentirely covered below the surface of the board in such a manner,consequently, that when the slide occupies its zero-position the upperhalff: of the track or groove ofthe slide b will be entirely open. Thebot-tom of the said groove supports a numeral scale divided into 100s upto 1000 with intermediate division lines for every 50. This scale,however, may also be drawn on the surface of the slide b or on the faceof the board along the edge of the groove. In any case the initial pointof the scale must be at the transverse line a when the slide occupiesits zeroposition.

Direct registration of scores below the line;7 i. e. below the tranverseline ais effected by means of two other' slides, viz a slide 0l to t-heleft of the slide b (see Fig. l) and a slide e to the right of the slideb, the said two slides Z and e being placed at one and the same depthbelow the surface of the board (Fig. 2) The scale corresponding to theslide d is placed on the surface of the board with it-s zero-point atthe transverse line a, and extends downward from the said line along theedge of the groove f of the slide, and is dio0 vided into 10s up to 100.In corresponding manner the scale of the slide e extends downward belowthe transversel line along the groove. g of the slide e, and is dividedinto units up to 10. If the scale of the slide d were divided into unitsup to 100, the slide e and the Vcorresponding groove g might bedispensed with. The scales may also be disposed at the bottom of theslide grooves or on the slides proper.

At its zero-position the slide d is covered entirely by a slide l,disposed at a higher level, and the slide e is similarly covered by acorrespondingly disposed slide z'. These two slides h. and e' are of thesame length as the slides d and e, and their scales are disposed on thesurface of the board alongside the grooves concerned and are divided 1nthe same manner as the scales for the slides d and e, but theirzero-points are disposed above 110 l which numerals, in combination withthree zeros printed on .the surface of the board to the right of thewin-dow, indicate the entirenumber of full thousands gradually scored byadjustments ofthe slide fb. The slide j, when in its zero-position,shows the figure inthe window and is in factadjusted so as to" show 1000when this figure has been Y from celluloid', will move perfectlyindependmay easily be gripped by two fingers.

reached on the scale of the slide I), and the' slide o is simultaneouslypushed back into its zero-position, in' such a manner that it will againbe ready to sum up the scored 100s, 50s etc. The small lower slide lcshows, through a small window, the number of games won, the'said slidebeing adjusted, Elfter the finishof each game, to show the number of thesame.

The scoringboard,'in the construction i1-v lustratjed, is supposed to bemade from five celluloid sheets placed on top of each other and formedwith the required number of slots serving as tracks for the slides andwith the required observation windowsfand the sheets are then joinedtogether so as lto form a unit. It will easily be understood that bysuch construction of the board the several slides which are likewisesupposed to be made ently of each other in their individual grooves ortracks. Their adjustment is effected by means of knobs Z attached to theslides and projecting through the slots in the board so so far above thesurface of the latter that they In order to facilitatethe properadjustment-of the slides @and to increase Iread-ing facility, the twosets of slides b, d and e ought to be differently coloured, 'forinstance red for of neutral colour, or vice versa. The slides z. and z',on the contrary ought to be of the same colour as the board, but theirgrooves above the line a should be coloured similarly to the dtherslides belonging to the same set.

At topof the board there is-provided a ruled space for notation of theresults of the individual rubbers,I and at bottom a table of trickvalues is printed."

During the play the scoringboard is used` for instance in the followingmanner, after all the slides have been placed in their zero- `positions.If during lthe first deal They gain 150 points above the line, the slideof the They set is adjusted at 15,0; then, if during the second \deal Wegain 300 points above the line, the slide b of the We the third dealThey win three hearts, y

i. e. 24 points below the line, the slide d is set on 20 and the slide eon 4. The State of the game thus assumed by way of example is shown inFig. 4l. If then during the fourth deal They make 50 points above theline, the slide b of the They set mustbe changed from its position (150points) to the position 200, and if We in the fifth deal win 100 pointsabove the line, the slide bof thel system We has to be moved from itsposition (300'points) into the position 400. If then during the sixthdeal We .attain .4 spades, i. e. 36 points below the line, .whereby thefirst game according to the rules of play .is finished, the slides dande of thel VVe. set aremoved to 30 and 6, respectively. As a new gamehas now to be begun, the

rules require that the score (24 points) of When the next new notationbelow thel line for They is marked by pushing downward the slides'd ande, the initial points of these notations will be the lower ends of thejust adjusted slides hand z' etc. When the score isy to be finallysettled at the end o f the rubber, the slides hand 'i are pushed down soas to cover completely the slidesd and e,

and the result may then'be read above the horizontal line a by additionof the readings on the two sets of slides`y', b, h and i separately, thesaid readings giving the gures representing 1000 lOs and units. f v

Having now particularly described and ascertained the nature of my saidinvention and in what manner the same is to be performed,

I declare that what I claim is They, blue for We, when the board is j l.A scoring device for bridge, comprising a support provided with atransversedivision Aline and with 'a plurality of longitudinal tracksintersecting such line, each track porimmediately' s, s, 50's,l
